Ronald Story's original The Encyclopedia of UFOs (1980) was heralded as the standard reference work on the subject for two decades. He is based in Seattle, Washington, USA and can be contacted through the website www.ronaldstory.com.

From the back cover:

This is the definitive A-Z guide to all things alien, from the first-ever-recorded incidents of close encounters to the latest information on world-wide UFOria. Over 400 fascinating entries cover everything from the incidents and witnesses involved to the concepts at stake and experts' personal position statements.

Entries from all the top thinkers in the fields of UFO research and SETI (the search for extraterrestrial intelligence), including Jerome Clark, Erich von Daniken, Hilary Evans, Timothy Good, John Mack, Nick Pope, Jenny Randles, Carl Sagan, Whitley Strieber, and Jacques Vallee.

Exactly what happened on JAL Flight no 1628, in the Lakenheath-Bentwaters Episode, or at Roswell? What do people mean by the Fantasy Prone hypothesis, mind control by aliens or the Prison Earth theory? And what do the top thinkers of our time really think about the question of extraterrestrial encounters? The Mammoth Encyclopedia of Extraterrestrial Encounters is more than just a history of witnesses and incidents - it is the ultimate source book on the subject.
